XP Network cannot access certain pages?

[Guest]

I have created the following home network in my new house (in the UK).

DSL internet from Virgin

LingSys Router WAG54GS

Ethernet connection to Win 2000 Pro Laptop (and then thru VPN)
Ethernet connection to XP Desktop
Wireless connection to another XP Desktop

PROBLEM: the two XP machines cannot load pages from specific Web Sites, for
example microsoft.com! Other websites load fine, although eventually some
link to another page won't connect.

The W2K Laptop connects fine to all sites, hence my ability to post in this
forum.

I have tried removing all firewalls and have scanned both for spyware, but
no luck. Both XP machines worked fine in the USA thru another LinkSys router.

Any suggestions would be greatly appreciated as the LinkSys, Dell and Virgin
support sites have all given up!

Thanks

Greg

we have seen many DSL lines have similar issue because of MTU. I could check MTU first. this link may help,

Robert, you hit the nail on the head!

when I set my routers MTU to Automatic, instead of the 1458 required by
Virgin DSL, suddenly the XP machines worked fine, accessing those troublesome
pages. Even my VPN (which I temporarily lost) came back, and seems to
connect fine.

So Thank You Very Much

cannot access secure websites

Hi I am a new joiner here !

I have a Linksys Wireless router 54G and I use AOL broadband for DSL.

I cannot access secure sites eg, Barclays Bank, Microsoft Hotmail etc....

Ive looked in to all possible ways of resolving this but comming across this website interested me as it could be my MTU on the router???

My MTU is set to 1400 and for about 4 weeks now there are 3 machines that cannot access those websites in Internet Explorer?

I would be very greatfull for any help and advice

Thank you

Annabelle
